RV125L Charging

[malky]

Hi all,
got a 1973 RV125L and getting some electrical issues with it - runs fine but indicators have stopped working suspect flasher unit - but the odd thing is if I put a multimeter across the battery with the engine running I'm getting a reading of up to 14 v ! the bike is running a 6v system - anyone got any ideas what is going on here

nobody got any ideas on this then?

Wiring diagrams for the 1977 RV90 & RV125 are here: viewtopic.php?f=29&t=4743&start=0

Wiring diagram for an earlier RV125 is here: http://www.2strokeworld.com/forum/index ... ic=20322.0

Not sure how your RV125L wiring compares to the above.

The earlier diagram shows a different ignition switch & no voltage regulator.
It shows that a resistor is used as a substitute load when the lights are off.
Would seem reasonable that the early RV125 did not have a voltage regulator & the later models did.

Both wiring diagram show a mixed AC/DC design with a half-wave rectifier.
Some components run on DC & others run on AC.
The AC powered components are only powered when the engine is running.
The headlight runs on AC -- so it works only with the engine running.
The flasher runs on DC.

Does your bike have a voltage regulator?

A PO may have modified the electrical system.
Have you confirmed that you have a 6V battery & the light bulbs are 6V?
How many diodes are in the rectifier?

Answered elsewhere. If it works, I'll post a link. If it doesn't I never said a thing!!!

Thanks guys -am going to try and check a few things out at the weekend if all goes to plan -I know the electrical system has never been touched as the bike is totally original and has only done 2k miles from new
